ETHER_ADDR_EQUAL_64B(9) Network device support ETHER_ADDR_EQUAL_64B(9)NAMEether_addr_equal_64bits - Compare two Ethernet addresses
SYNOPSIS
bool ether_addr_equal_64bits(const u8 addr1[6+2], const u8 addr2[6+2]);
ARGUMENTS
addr1[6+2]
Pointer to an array of 8 bytes
addr2[6+2]
Pointer to an other array of 8 bytes
DESCRIPTION
Compare two ethernet addresses, returns true if equal, false otherwise.
The function doesn´t need any conditional branches and possibly uses
word memory accesses on CPU allowing cheap unaligned memory reads.
arrays = { byte1, byte2, byte3, byte4, byte6, byte7, pad1, pad2}
Please note that alignment of addr1 & addr2 is only guaranted to be 16
bits.
